Abstract

Vector-borne diseases pose a significant threat to human and animal health worldwide, with arthropods, including fleas and lice, acting as key vectors for transmitting various pathogens. In Uzbekistan, where millions of domestic dogs coexist with humans, the diversity of vector-borne pathogens carried by ectoparasites remains largely unexplored. This study aimed to investigate the diversity and prevalence of lice and pathogens carried by fleas and lice collected from domestic dogs in Uzbekistan. Ectoparasites were collected from 77 dogs across five regions and subjected to morphological identification and molecular analysis. The 47 lice collected were identified as Trichodectes canis Fabricius, 1780 (Psocodea: Trichodectidae), Linognathus africanus Kellogg and Paine, 1911 (Psocodea: Linognathidae) and Bovicola bovis Linnaeus, 1758 (Phthiraptera: Trichodectidae), alongside with 197 fleas. Notably, L. africanus was detected for the first time on dogs worldwide. Molecular screening detected Rickettsia spp. in 27.9% fleas and 44.7% lice, Dipylidium caninum Linnaeus, 1758 (Cyclophyllidea: Dipylidiidae) in 1.5% of fleas and Bartonella spp. in 0.5% of fleas. Sequencing confirmed Rickettsia asembonensisMaina et al., 2016 (Rickettsiales: Rickettsiaceae), Rickettsia helvetica Beati et al., 1993 (Rickettsiales: Rickettsiaceae), Rickettsia monacensis Simser et al., 2019 (Rickettsiales: Rickettsiaceae), D. caninum and Bartonella clarridgeiae Lawson and Collins, 1996 (Hyphomicrobiales: Bartonellaceae). These findings highlight the potential role of dogs as reservoirs for vector-borne pathogens and emphasises the need for further research to inform effective disease control strategies.

乌兹别克斯坦自由放养的狗身上的虱子以及跳蚤和虱子传播的病原体的多样性。
病媒传播的疾病对全球人类和动物健康构成重大威胁,包括跳蚤和虱子在内的节肢动物是传播各种病原体的主要载体。在乌兹别克斯坦,数以百万计的家犬与人类共存,但体外寄生虫携带的病媒传播病原体的多样性在很大程度上仍未得到研究。本研究旨在调查从乌兹别克斯坦家犬身上采集的跳蚤和虱子所携带的虱子和病原体的多样性和流行率。研究人员从五个地区的 77 只家犬身上采集了体外寄生虫,并对其进行了形态鉴定和分子分析。收集到的 47 只虱子被鉴定为 Trichodectes canis Fabricius, 1780(Psocodea: Trichodectidae)、Linognathus africanus Kellogg and Paine, 1911(Psocodea: Linognathidae)和 Bovicola bovis Linnaeus, 1758(Phthiraptera: Trichodectidae),以及 197 只跳蚤。值得注意的是,L. africanus 是首次在全世界的狗身上发现。分子筛查在 27.9% 的跳蚤和 44.7% 的虱子中检测到立克次体,在 1.5% 的跳蚤中检测到犬二联蚤(Dipylidium caninum Linnaeus, 1758)(Cyclophyllidea: Dipylidiidae),在 0.5% 的跳蚤中检测到巴顿氏菌。测序结果证实了 Rickettsia asembonensisMaina 等人,2016 年(立克次体科:立克次体属)、Rickettsia helvetica Beati 等人,1993 年(立克次体科:立克次体属)、Rickettsia monacensis Simser 等人,2019 年(立克次体科:立克次体属)、立克次体科:立克次体属)、D. caninum 和 Bartonella clarridgeiae Lawson 和 Collins,1996 年(表皮微生物科:Bartonellaceae)。这些发现凸显了狗作为病媒传播病原体的潜在贮藏库的作用,并强调了进一步研究的必要性,以便为有效的疾病控制策略提供信息。

期刊介绍: Medical and Veterinary Entomology is the leading periodical in its field. The Journal covers the biology and control of insects, ticks, mites and other arthropods of medical and veterinary importance. The main strengths of the Journal lie in the fields of: -epidemiology and transmission of vector-borne pathogens changes in vector distribution that have impact on the pathogen transmission- arthropod behaviour and ecology- novel, field evaluated, approaches to biological and chemical control methods- host arthropod interactions. Please note that we do not consider submissions in forensic entomology.
